Description
FIELD OF THE INVENTION

The present invention relates to a cosmetic and/or dermatological preparation with a content of licochalcone A and surfactants, in particular for improving the condition of irritated skin or scalp, for example after or during the application of such a preparation.

BACKGROUND OF THE INVENTION

The desire for a clean and cared-for appearance is probably as old as man. Bad skin and an uncared-for hair costume offer ideal breeding grounds and homes for pathogens and parasites of all types. The desire for body hygiene was continuously intensified when, in the 1960s, besides the “classical” soap, it was also possible to formulate liquid cleansing compositions with newly developed synthetic surfactants. Since this time, we can no longer imagine daily life without bathing and showering, and a large number of products for cleansing the various parts of the body are nowadays available to the consumers.

Cosmetic and/or dermatological cleansing preparations are generally applied in the form of a foam with water to the parts of the body to be cleansed. The basis of virtually all cosmetic or dermatological cleansing preparations are washing-active surfactants. Surfactants are amphiphilic substances which can dissolve organic, nonpolar substances in water. They are characterized by ambivalent behaviour towards water and lipids: the surfactant molecule comprises at least one hydrophilic group and one lipophilic group which permit the positioning at the interface between these two classes of substance. In this way, surfactants ensure a reduction in the surface tension of the water, wetting of the skin, easier soil removal and dissolution, easy rinsing and—if desired—also foam regulation. The basis for the soil removal of lipid-containing soiling is thus given.

The hydrophilic moieties of a surfactant molecule are mostly polar functional groups, for example —COO−, —OSO32, and —SO3−, whereas the hydrophobic moieties are generally nonpolar hydrocarbon radicals. Surfactants are generally classified according to type and charge of the hydrophilic molecule moiety. In this regard, it is possible to differentiate between four groups:

    • anionic surfactants,
    • cationic surfactants,
    • amphoteric surfactants and
    • nonionic surfactants.

Most cosmetic and dermatological cleansing preparations are in the form of liquids of greater or lesser viscosity (cleaning washes, gels, and milks) or in the form of a solid (e.g. soap and washing synthetics). They are generally applied using the hands or fingers to the skin or the skin appendages (e.g. hair, nails).

For the cleaning of keratin fibres and/or skin, use is generally made of shampoos and shower gels and/or face cleansers which comprise surfactants or surfactant mixtures and care substances. Such surfactant-containing cleansing and/or shaving compositions (e.g. shampoos, shower gels, shaving foams, etc.) are subject to a large number of requirements which these preparations should satisfy at the same time: these preparations are expected to be skin-compatible and to leave behind a pleasant feel on the skin following application to the skin. This skin, in particular the epidermis, being a barrier organ of the human organism, is subjected to external effects to a particular degree. Such effects can exert irritation to the skin which, in people with sensitive or injured skin, can lead to reddening, tightness, burning and/or itching. Such effects include UV irradiation, mechanical stresses, and contact with irritative substances. Areas of skin which are subjected to these effects in a largely unprotected way and react sensitively include, in particular, the scalp. Besides the solar irradiation to which the scalp is exposed with greater or lesser protection depending on the hair style, mechanical stresses resulting from combing, brushing, and cutting (including shaving), the scalp is also subjected to contact with irritative substances. Besides chemicals which are used for colouring the hair or permanent waving, mention may be here in particular of the surfactants which are used during often daily hair washing. After hair washing, the hair and/or the scalp is often subjected to further treatments which care for the hair and which are intended to stimulate the scalp, but which likewise lead to the described undesired effects.

The surfactants and surfactant mixtures used are composed of anionic, amphoteric and/or nonionic surfactants. The usual use concentrations of the surfactants up to about 25% and the application conditions customary for body- and hair-cleansing, modern shampoo compositions have good skin compatibility. Nevertheless, in the case of a sensitive scalp or increased use (sportsman), scalp irritations may result. The use of relatively small use concentrations or relatively mild surfactants does not represent a solution to this problem since losses in performance with regard to the foaming ability and the foam creaminess are always also associated with it.

Moreover, the formulations should be easy to foam and form a creamy, finely bubbled foam. However, such preparations as the prior art have the disadvantage that they fulfil these requirements in an only inadequately consistent manner. Good foaming products are generally less skin-friendly and leave behind a dry feel on the skin. Especially mild, skin-friendly products, in turn, generally do not foam well.

A further disadvantage of the prior art consists in the fact that, particularly in industrialized countries, there is an increase amongst the population in incompatibilities and allergic reactions towards a large number of chemicals and ingredients of cosmetics and dermatological compositions. Surfactant-containing cosmetic and dermatological preparations are also being affected by this development to an increasing degree since they can sometimes partly dissolve the protective lipid layer on the skin and, on the one hand, penetrate deep into the skin, on the other hand remain on the skin for a long time. For this reason, the concentration of surfactants in cosmetic and/or dermatological preparations should be kept as low as possible. In addition, there is a need for surfactant-containing preparations with varying surfactant composition since incompatibilities and allergic reactions are substance-specific and the people affected are thus given the option of using cosmetic and/or dermatological preparations with a composition which is matched to their incompatibility profile.

SUMMARY OF THE INVENTION

The object of the present invention was to overcome, or at least significantly reduce, the shortcomings of the prior art of surfactant-containing cosmetic and/or dermatological preparations, in particular of hair shampoos, shower gels, and shaving foams. The aim was to develop preparations which are skin-friendly and leave behind a pleasant feel (soft, cared for, smooth, clean) on the skin. At the same time, these preparations should foam easily and form a creamy, fine-bubbled, dense, stable foam.

Licochalcone A is a constituent of the extract from Radix Glycyrrhizae inflatae and is characterized by the following structure:

Like the liquorice (Glycyrrhiza glabra) approved within Europe, the plant species Glycyrrhizae inflatae belongs to the genus Glycyrrhiza, which belongs to the Fabaceae family (pea plants).

It has now been found, in a manner which is surprising and unforeseeable by the person skilled in the art, that cosmetic hair- and/or body-cleansing compositions comprising licochalcone A or an extract of Radix Glycyrrhizae inflatae and one or more surfactants, besides, if appropriate, further cosmetic and/or dermatological active ingredients, auxiliaries and additives, overcome the disadvantages of the prior art. By means of such preparations, the skin or scalp which comes into contact with the compositions during use is cared for in a particular way by improving the condition of irritated skin or scalp. The cause of irritated skin or scalp may be UV irradiation, mechanical stress and/or contact with chemicals. Contact with chemicals and in this connection mention is to be made quite specifically of frequent contact with cleansing surfactants, is a common stress factor for the skin or scalp, whose symptoms, such as reddening, burning, itching, are significantly reduced or eliminated by the products according to the invention without influencing the care properties and the quality and distributability of the composition in an adverse way. A condition improved in this way can be observed particularly in the case of surfactant-damaged skin or scalp.

DETAILED DESCRIPTION OF THE INVENTION

The extract of Radix Glycyrrhizae inflatae may be aqueous or alcoholic. The alcoholic extract is particularly preferred due to its effectiveness. Such extracts are obtainable, for example, under the names “Polyol Soluble Licorice Extract P-U” or “Aqua Licorice Extract P-U” from Maruzen Pharmaceuticals. The first-mentioned extract is an alcoholic extract which is in powder form. “Aqua Licorice Extract P-U” also comprises additional ethoxylated and/or propoxylated raw materials. In this connection, it is advantageous if these ethoxylated and/or propoxylated raw materials, which are added to the extracts by the manufacturer for various reasons, are not present in the preparation because their possible sensitizing potential can then not arise. In particular, the absence of PPG-6 (Nikkol PEN) is of great advantage. It is very particularly advantageous to start from an alcoholic extract, as can be obtained under the name Polyol Soluble Licorice Extract PU (INCI name Glycyrrhiza Inflata) from Maruzen. The extract of Radix Glycyrrhizae inflatae comprises a content of about 25% licochalcone A. It is thus possible to prepare cosmetic or dermatological preparations for body- and hair cleansing which have exceptional mildness. Beyond these effects, it was surprisingly found that the preparations according to the invention can be used advantageously for the treatment and prophylaxis of post-inflammatory skin conditions triggered by surfactant damage to the skin. Furthermore, these formulations are suitable for the treatment of skin reddening, in particular rosacea. It is preferred if the content of licochalcone A or extract of Radix Glycyrrhizae inflatae is at least 0.0001% by weight, particularly preferably 0.0005% by weight, very particularly preferably 0.001% by weight, very extraordinarily preferably 0.01% by weight, very extraordinarily particularly preferably 0.05% by weight and at most 10% by weight, particularly preferably 5% by weight, very particularly preferably up to 2% by weight, very extraordinarily particularly preferably 0.1% by weight, in each case based on the total weight of the preparation.

In addition, it is preferred if the surfactants used are anionic, cationic, zwitterionic, amphoteric surfactants, particularly preferably anionic and zwitterionic surfactant and/or the combination of ionic surfactants with nonionic surfactants. It is particularly preferred if the total amount of surfactants is from 1 to 50% by weight, particularly preferably 5 to 30% by weight, based on the total weight of the preparation. It is very particularly preferred if the ratio of the total amount of saccharides to the total amount of surfactants is from 1:1000 to 10:1, preferably from 1:300 to 1:1 and very particularly preferably from 1:100 to 1:5.

It is also preferred if sodium laureth sulphate is used as surfactant on its own or in combination with further surfactants, particular preference being given to the combination of sodium lauryl ether sulphate and cocoamidopropylbetaine and/or other surfactants, such as, for example, alkyl polyglucosides, amphoacetates, sulfosuccinates.

In addition, it is preferred if such a composition is stored in a foam dispenser and is applied from this. It is particularly preferred if such a composition is used as impregnation for an insoluble substrate.

Preference is also given to those compositions which are suitable as hair-cleansing compositions and additionally a polymeric quaternized ammonium salt of hydroxyethylcellulose which has been modified with a trimethylammonium-substituted epoxide (INCI: Polyquaternium-10) (Ucare Polymer JR 400 from Amerchol) and/or a depolymerized guar gum derivative which has been quaternized (INCI: Guar Hydroxypropyl Trimonium Chloride) (Jaguar Excel from Rhodia) is present in the preparation, particularly preferably in concentrations of from 0.01 to 5% by weight. Moreover, a combination of such a composition with an insoluble substrate is preferred.

The invention also comprises the use of such compositions for the treatment, in particular for improving the condition of predamaged skin or scalp, preferably skin or scalp damaged by surfactants, for the cleansing and/or care of the skin and skin appendages, as shower, foam and/or tub bath, as hair shampoo, as shaving foam, as face-cleansing preparation for the removal of decorative cosmetics, and a product comprising such a composition contained in a package on which there is writing, where the writing indicates at least one of the specified uses.
